I found some larger stepper motors that I had salvaged from a large dot matrix printer years ago. They are rated at 4.4V 1.15 A. However I have discovered that the EasyDriver chops and current limits the output so you can run these motors at much higher voltage then they were intended to run at. This can come in very handy in CNC operations because under low load you can drive them very fast and have great response. I plan on redesigning my linear actuators to take advantage of these larger steppers. Someone on Chiphacker coincidently asked this question the other day as well so I thought it was a good time to test my theory.
